Obsessive-Compulsive Disorder (OCD)

What Is It?

In obsessive-compulsive disorder (OCD), a person is troubled by intrusive, distressing thoughts (obsessions) and feels the pressure to carry out repetitive behaviors (compulsions).

Neuroscientists believe that the brain pathways involved with judgment, planning and body movement are altered in OCD. Environmental influences, such as family relationships or stressful events, can trigger or worsen OCD symptoms.

Daily Health Tip

Keep learning

A lifelong habit of learning and engaging in mentally challenging activities seems to keep the brain in shape. Intellectual enrichment and learning stimulate the brain to make more connections, increasing the density of nerve-to-nerve connections. That means the "educated brain" may possess a deeper well of connections and be able to withstand more damage to the brain from a small stroke without causing loss of memory or thinking skills.
